IMPROVEMENT IN WAGON-LOCKS.

Specification forming part of Letters Patent No. 48,228, dated June 13, 1865.

To all whom it may concern.-

Be it known that I, JOHN F. YATES, of Mooresville, Morgan county, and State of Indiana, have invented a new and useful mode of locking Wagons in going down a mountain, and of preventing wagons from running backward in going up the mountain when horses are stopped for rest; and I do hereby declare that the following is a full, clear, and exact description' of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, of Which- Figure 1 represents a perspective view, and Fig. 2 a section. The red marks ofFig. 2 explain the operation.

To enable others skilled in the art and science to fully understand my invention, I shall proceed to describe it.

A A A A are the wheels. B B are the axles. G O are the bolsters; D D, the hounds; F, the head of hounds; K, the tongue. J is the doubletree. G H are the rob-bars. I is the slider. U U are the stay-chains. T T are the braces. V is the ham mer-strap, with the hammer a and staple m. N is the front rod. M is the lever. O is a brace forthe lever. P is the rear rod, which is fastened on one end to the lever M, and on the other to the rob-bar H by b. RR are the slides. R has abolt, f, passing through rob-bar H, and R has a bolt, 0, passing through rob-bar G. S are the pulleys, with bolts d d running through rob-bars G and H. h is a snake-iron, and -i is the drop-lock. g g, 850., are the hubs. 7c is the tongue-bolt, and w the stopbolt. h is the king-bolt.

It will be seen that when the horses hitched to'the wagon, in going down the mountain,

that the friction of these rob-bars increases as the weight increases. When arrived at the foot of the mountain, the horses will gradually stop pushing and begin to pull. In so doing they pull the tongue out to its former place, and raise the look. If the driver desires to back up, he puts the stop-bolt minto the tongue and front hounds, E E. By turnin g the horses at little one Way or the other, in going up the mountain, the longer end of the drop-lock I will fall to the ground and brace the Wagon,

thereby preventing it from running down, and

giving the horses a chance to rest.

What I claim as my invention, and desire to secure by Letters Patent of the United States,

The combination of the tongue K, the ton guebolt k, the stop-bolt :r, the front'rod, N, the lever M, king-bolt h, brace 0, rear rod, P, the robbars G and H, with their connecting-pulleys a 0L and slides R It, the hounds D D, the droplock t', with the snake-iron It, all arranged and operating substantially as described, and for the purpose set forth.
